I've got 5 fish, 3 cory catfish (bottom feeders that clean the gravel) a clown loach and a plecostomous that is nearly double the size than when i got it. 2 of the cories are from a project i was trying to do in an attempt to breed them (i failed) and the other is for maintenance. The loach is there for entertainment (it plays dead 4 times a day, it's what they do) and the pleco was just purchased on a whim. We usually don't have the best luck with plecos, but for whatever reason this one grew to a monstrous size, possessing thick serrated scales to protect it from a danger that never comes. They say that pets tend to reflect their owners personality, and i can see that, All of the aforementioned fish are bottom feeders, usually an insult but i see it as another word for "resourceful".
